Reimagining Civilization with Floating Cities

The Seasteading Institute is a nonprofit think-tank promoting the creation of floating ocean cities as a revolutionary solution to some of the world’s most pressing problems: rising sea levels, overpopulation, poor governance, and more…

Seasteading is building floating societies with significant political autonomy. Nearly half the world’s surface is unclaimed by any nation-state, and many coastal nations can legislate seasteads in their territorial waters.

Why Seastead?

Floating societies will provide the means for rapid innovation in voluntary governance and reverse environmental damage to our oceans. Seasteads will unleash the Blue Economy to create jobs and foster entrepreneurship.

The First Seastead

French Polynesia boldy led the world into the Seasteading Century when their leaders signed a historic agreement with our Institute to explore the possibility for a SeaZone, a floating legal entity designed to maximize personal and economic freedom, to empower island communities to adapt to sea level changes on their own initiative.

What Do Seasteaders Want?

We want free seas. There are as many reasons to seastead as there are problems to solve profitably. Eight “aquapreneurs” plan to enrich the poor, cure the sick, feed the hungry, clean the atmosphere, live in balance with nature, power the world, and live in peace.
